Hyoutan Pond is a great place to escape from the fast pace of everyday life. See if any water activities are on offer here, or just soak up the serene ambiance.
When you've finished up at this Saijo body of water, why not check out Kichijoji Temple, Imabari Ichihiro, and Asahi Brewery Shikoku? They're not far from Hyoutan Pond and also a favorite with many tourists.
